Subaru 75mm Heat Treated Crankshaft - WRX & STI 1998-2005 (V4-V8) EJ20

Introduced in November 2002, this crankshaft was a factory-fit component on all Japanese Domestic Market vehicles. For many years it was supplied balanced, cross-drilled and finished with nitride hardening, which made it a good budget tuning component.

In 2013 the crankshaft was superseded. Cross-drilling and nitride hardening were dropped from the manufacturing process and replaced with a more cost-effective form of heat treatment.

This JDM crankshaft is still considered the best standard option for all EJ20 engines, and the preferred choice before investing in more expensive billet crankshafts.
